Abstract
A microphone generates a voice signal based on air vibration. A vibration sensor generates a vibration signal based on vibration transmitted to a human body. An adaptive filter multiplies the vibration signal by a coefficient to generate a converted voice signal. A subtractor generates a residual signal that is a difference between the voice signal and the converted voice signal. The adaptive controller controls the adaptive filter to update the coefficient so that the residual signal becomes small at a first speed when it is determined to be a voice section, and controls the adaptive filter to update the coefficient so that the residual signal becomes small at a second speed slower than the first speed when it is determined to be a non-audio section, or supplies the adaptive filter control signal to the adaptive filter to control not to update the coefficient.
